Three-Party Controlled Authentication Semiquantum Key Agreement Protocol for Online Joint Consultation

Abstract: In Wise Information Technology of Medicine, to ensure both confidentiality and integrity of the data created during online joint consultations, and to solve the problem that ordinary users cannot afford expensive quantum devices and are vulnerable to man-in-the-middle attacks during communication, this article proposes a three-party controlled authentication semiquantum key agreement protocol, leveraging the […]

FPGA-Based Synchronization of Frequency-Domain Interferometer for QKD

In this article, we propose and experimentally demonstrate a novel synchronization method for quantum key distribution (QKD) systems. The method consists of maximizing the visibility of frequency-domain interference of optical sidebands about an optical carrier at the receiver node. The sidebands are generated by phase modulation of the optical carrier by an radio-frequency (RF) signal […]
